ntp synchronization failure seen during bootstrap

Could you please post /etc/ntp.conf from the bootstrap node?

ntp.conf file is attached.

The script which generates ntp.conf on bootstrap nodes does not verify if masternode_ip variable is non-empty: https://github.com/stackforge/fuel-main/blob/master/bootstrap/sync/usr/bin/fix-configs-on-startup#L51

As a result

server burst iburst

stanza is written to ntp.conf. ntpdate tries to interpret "burst" as a server name (which obviously fails).
However if the bootstrap node failed to get the master node IP the game is basically over: the bootstrap node
will be unable to contact the master. Having a valid ntp.conf won't help.

Not a bug, since we changed the cobbler profiles a lot during the debug.

This lead to the overwrite of the following kernel params which are used for the mcollective initialization as well as ntp configuration:

fuel-master # cobbler profile report --name=bootstrap | grep Kernel\ Options
Kernel Options : {'url': 'http://10.20.0.2:8000/api', 'mco_pass': 'eBO7EtXG', 'biosdevname': '0', 'mco_user': 'mcollective'}
Kernel Options (Post Install) : {}
